71M652X Software User’s Guide
The vectors associated with each interrupt source are displayed in Table 6-59.
The external interrupts 4, 5 and 6 are activated by a positive transition. The external source must hold the request pin
low (high for int2 and int3, if it is programmed to be negative transition-active) for at least one MPU clock period.
Afterwards, it must be held high (low) for at least one MPU clock period to ensure the transition is recognized and the
corresponding interrupt request flag is set.
